Vinyl Acrylic Binders & Resins

Vinyl acrylic binders and resins are economical products that find extensive usage in interior architectural paints and caulks, adhesives and sealants, paper and textile binders, paper saturants, engineered fabrics, and pigment dispersions. With the unlimited variability in monomer options and copolymer ratios, vinyl acetate-acrylic copolymer binders allow the design of products with a wide spectrum of cost and performance profiles.  The role of the binder resin is to bind the pigments into a tough, continuous film and to promote the adhesion to the substrate surface while resisting wear and blistering etc.  Vinyl acetate monomer achieves cohesive strength in a binder at a low cost, while acrylic monomers like butyl and 2-ethylhexyl acrylates enhance the performance of copolymers by improving flexibility, water resistance, adhesion, scrub, and stain resistance and outdoor weathering.

Durable, Ambient Temperature, Self Crosslinkable Acrylic Emulsions Based on DAAM/ADH

The leading crosslinking technology for acrylic emulsion polymers is ambient temperature crosslinking chemistry based on diacetone acrylamide (DAAM) and adipic acid dihydrazide (ADH) monomers. This technology, known as “keto-hydrazide crosslinking,” involves the direct reaction of the pendant ketone moiety on the DAAM-acrylic polymer segment with the hydrazide moiety of the ADH, with the evaporation of water in the film-forming process. 

The highest adoption of this ambient temperature, self-crosslinking technology has been in high-durability paints and coatings for architecture, wood and concrete surfaces, and more. The DAAM/ADH pair is also used in crosslinkable sizing agents, thickeners, adhesives, and sealants.
